EFzFflABLEy PIPE-JOINT. i

-' Application filed September 17, 1904.. Serial No. 224,794:-

loa/,Z whom t may concern.-

Be it known that I, ARTHUR C. LYNCH, a citizen of the United States, residing at Richmond Hill, County -of Queens, State of New York, (whose post-office address is the same,) have invented certain new and usefulv Improvements in Separable Pipe Joints, of which the following is a full, true, and concise specification.

This invention relates to the construction of separable joints for pipes and tubes, which are cheap of manufacture, eiiicient in action, and convenient of manipulation, as will presently be made toy appear more fully, and the invention also involves other features hereinafter pointed out in the appended claims.

- Referring to the drawings, Figure 1 represents a side elevation of a pipe-j oint embodying this invention, and Fig. 2 is a transverse section of the same on the line 2 2 of Fig. 1.

The joint` is formed of the two ends of pipesection, such as 1 and 2, which telescope one within the other, as shown, and the overlapped portions of the two sections are embraced by a binding-strap 3, the function of which is to bind the female member of the joint closely against the other member. The

strap may be of various constructions so long .jso

as it serves the above purpose, and in the drawings it is shown as a flat `strip of metal with outturned perforated ends provided With a bolt and thumb-nut 4, whereby the same may be easily drawn together. The female member is cut away or recessed at its end where it overlaps'the male member in such manner that the remaining internal projecting end 5, which may be of any width desired,but of less length thanthelength of the overlaplped portion, will bind forcibly upon the 'ma iiuence of the tightened strap, and the recess may be made of sufficient circumferential dimension to permit the strap to bear through it directly a ainst the inner male member, thereby pro ucing a construction especially secure in that the tendency ofthe two sections to separate willskew the strap and inthe drawings, and the strap is suitably at" tachedi to the4 projection 5, although it may Specication of Letters Patent.

l be secured to the male member, if so desired.

The attachment of the pipe to the stra may be according to any approved metho provided that such connection will vbe secure when the strap is tightened. I have preferred a method by which the strap may be easily reversed in position with respect to the j ointthat is to say, one in which the thumb-nut may be readily disposed upon either side of the joint without necessitating the removal of its bolt. This attachment consists in providing the strap with a projecting pin 6,

adapted to engage with one or the other of twol apertures 7 on opposite sides of the projection 5, according to 'whichever sidel the thumb-nut'is desired to be located; but it would be obvious that a single central aperture would be suflicient to effect the same re- 7o sult and also that the relative positions'of pin and recess might be reversed-fi. e., the pin vmight be placed upon the pipe and the'aperture in the strap, if desired.

With the above construction two pipe-sections maybe quickly brought together in telescoping relation, the strap having been previously placed over one of them in such position as to bring the thumb-nut on the desired and most convenient side. U on tight-v ening the strap by screwing the t umb-nut the parts will be brought together into secure locked condition; but they may be easily disassembled upon loosening the thumb-nut.

` Having described my invention, what l claim, and desire to secure-by United States Letters Patent, is-

l. A .pipe-joint comprising male Vand female members, a recess formed in the end of the female member to leave an integral projection overlapping the male member, and a.

binding-strap embracing said projection and male member. j

2. A pipe-joint comprisingfmale andfemale members, a recessformed in the end of the female member to leave an integral' projection `thereon overlapping the male member, a binding-strap attached to said projection embracing the male member and means 3. A pipe-joint comprising male and female members, a projection on said female member formed byrecessing the end of the same and a binding-strap embracing said projection and the male member and unconconsisting of an aperture in one part and a nected with said female member on the side of pin on the other engaging the same.
